i had serious issues with elbow tendonitis around a year ago (pain radiating up from elbow to shoulder),, at the time i just used to concentrate on routes, but more than two days in a row bouldering would always bring it back (font and grit being the worst aggravators). i read an article and spoke to some physio friends who claimed that all the repetive pronated (palm away) actions involved in climbing lead to imbalances. while sitting out a month with a tweaked finger i did lots of supinated (palms up) exercises, biceps curls, writs curls and pull-ups. after the month off i took another month to slowly ease back into things, avoiding consecutive days climbing and throwing myself at compression-style bouldering. ive just come back from a 3 month trip to the states involving 5 days a weeks climbing and only suffered a very mild case on my fourth consecutive day at bishop, which a days rest sorted. that is the only time i have felt anything amiss in the last six months. my diagnosis is that some rest, supinated exercises and a gentle return gave my tendons time to catch up strength wise with my muscles (i could of course be chatting shit, as i have no medical training). fingers crossed for the future.....
